Although the book was written back in 2010, it is sadly still VERY relevant to the Voice-over-IP (VoIP) systems deployed today. I would have loved it if vendors would have made systems so much more secure that this book could be forgotten about... but the security concerns have only increased in the time since the publication. Even six years later it still offers relevant advice and suggestions about how to make sure your IP communication systems are as secure as possible.

I am a big fan of buying ebooks directly from O’Reilly because doing so gets you:

Here's a great chance to help learn more about how to secure Unified Communications / VoIP systems - or to buy this book for someone you think would like to learn more on the subject.

The awesome aspects about ordering ebooks directly from O'Reilly include:

DRM-free - you can read the ebook on as many different devices as you want... and you don't have to mess around with silly licensing systems.

Multiple formats - you can download the book in ePub, Kindle, PDF.

Free lifetime access - you don't have a limit on when you can download the book and you can always go back in and get it.

Free updates - whenever there are updates to a book you get a notification and can easily download the update.

All around it's just a great system for working with ebooks... and yes, I'm an author for them so you might expect me to say this, but I'm also a consumer who purchases ebooks and I like their system better than any of the other ones out there that I've tried.

I'll note on the "Free updates" part - I don't yet have any current plans to update "Seven Deadliest UC Attacks" (unlike my "Migrating Applications to IPv6" book that will see an update in 2014) but if I do work on an update at some future point, ebook purchasers through O'Reilly would be the ones to easily get an update (versus print or ebook through other systems). And you will get updates for any other ebooks you purchase.

It's a great deal - and I'd encourage you to stock up on ebooks from O'Reilly's site today!

Amazon.com recently started making book sales data from Nielsen BookScan available through their "Author Central" portal - and it yields some interesting data for those of us writing books. Now, it's not complete data as BookScan only covers about 75% of the online and offline booksellers, and it does NOT include ebooks, Kindle editions, etc. Still, it can provide some fun facts like the fact that the last purchases of Seven Deadliest Unified Communications Attacks were in New York, Chicago and L.A.:

What's cool for me as an author is that it also aggregates and displays data across all my books. Now... my books are not exactly NY Times Bestsellers (what? you mean the world isn't racing to learn about UC security? :-) so the data isn't as exciting as it would be for those with more mainstream books... but it's very cool to see. Thanks to Amazon for making this data available (for free) to all of us who write books!

I've had a good number of people ask me about a Kindle version... and it obviously makes a good degree of sense given that it's a technical book for a technical audience, many of whom may have e-readers.

I don't own a Kindle, but I do have both an iPad and an iPhone - and the Kindle reader is available for free for both of those - so I am looking forward myself to seeing my book on my iPad as an "e-book".

What about you all? Do you want to buy the book in paper/treeware form? Or do you want an ebook version?

Silly me! I naively thought that maybe this time around the "launch" of the book could actually be nailed down to "a day".

You see, back in the 1990's and early 2000's when I wrote my other four books, it was a different era. Amazon.com wasn't quite the enormous industry player that it is today. You sent your text and edits into the publisher and then sometime a book showed up at your house... and sometime after that it appeared in local book stores. Sometime... whenever...

Fast forward 8 years and I thought it might be different now. I thought the launch date could be nailed down. I watched friends like Chris Brogan, Mitch Joel and Steve Garfield all focus on "launches" of their books on specific days... and figured it would be similar for mine.

Nope.

Now, granted, all of their books are targeted at the larger marketing/communications audience... and maybe they planned for a date after availability... and given everything else on my plate, I didn't really spend that much time working on a launch plan. I just sort of thought it might work out easier.

The editors, publicity folks and others at Syngress were all great. They told me...

Only a few hours after writing my post today saying that I still didn't have a copy of the book, a UPS truck pulled up outside my house and dropped off a box...

Having submitted the chapters back in November, December and early January ... and then worked on proofs of the pages in February and early March... it's great to finally hold the final version in my hands.
